cANcELlN e-STAMP.

SPECIFICATIONforming part of Letters Patent No.V 293,510, dated February1,2, 1884.

` Application filed September 1l, 1883. (No model.)

To @ZZ whom, it may concern,.-

Be it known that I, PETER PFEIFER, a citizen of the United States,residing at Durham ville, in the county of Oneida and State of New York,have invented certain new and useful' `Improvements in Canceling-Stamps,of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention relates to improvements in canceling and postmarking ,anddating devices for use upon postal and other stamps. The object of myinvention is to provide a simple, cheap, and durable device which willmutilate, permanently deface, and cancel stamps upon which it is used,the degree of mutilation being determined or regulated by a set-sc"rewwhich determines the depth toA which the mutilating teeth shall enterthe stamp or `other surface to be defaced.

Figure 1 isa side elevation of my improved canceling and post-markingdevice. Fig. 2 is avertieal sectional view. Fig. 3 is an edge view, andFig. 4 is an end or bottom view.

Referring to the drawings, A is a tube, serving as the body or handle ofthe device, in which is secured the flexible bar B, the upper end ofsaid bar being screw threaded and adapted to pass through the cap C, toreceive the thumb-nut D, by which the bar B is adjusted within the tubeA. The bottomof the tubeA is closed with a cap or sleeve, E, securedthereon bya screw, a, the face of cap E being provided with apertures bb b, which receive the serrated feet or prongs of t-he bar B, as willmore fully appear. The filling pieces or face F of the cap E areserrated in a reverse direction from the serrations on the prongs of thebar B, and by which the paper or stamp is'held while the serrations lonthe prongs of the bar are cutting or'defacing the stamp or othersurface.

G is a sleeve which encircles the tube or handle A, and is held in anelevated position by the spring H. Inlay, however, use a spiral springin lieu of the spring shown. The lower end of the sleeve G is providedwith a projecting flange, I, to the Linder side of which is secured abar or lug, L, which projects through a slot, c, in the tube A, so as tocome in contact with the bend or inclined portion d of the bar when thesleeve G is pushed downward on the tube A. The lower portion of the barB is bent at right angles and divided into three or more feet or prongs,c e e, which are serrated on the lower edge, the serrations extendingina reverse direction from the serrations on the face of the cap E, andwhen thrust forward by and cap O, so that a thin skin of the stamp canbe removed without injuring or cutting the envelope or the contents ofthe same.

which has elasticity enough to bring the. feet or prongs c e into theproper working position the arm or lug L coming in contact with the Thebar B is made of steel or other suitable materialv when the lug or arm Lis not in contact with the incline d. The flange I on the lower portionofthe sleeve G serves as a guard to prevent the hand of the operatorfrom slipping down.

M is a short section of tubing secured to the cap E by brazing, or inany suitable manner, in which the post-mark and date type are placed,and when the device is placed on the inkingpad the serrated prongs, aswell as the type, will be inked, and in the process of mutilation .theserrations on the prongs e will deposit ink on the stamp, and thus makethe cancellation of the stamp more complete.

It will be noticed that the nut D extends through the cap C, and has abushing, f, secured thereto, which prevents the bar B frombeingforcedupwardin the cancelingoperation.

Having thus described my invention, what I claim, and desire to secureby Letters Bateut, is

1. In' a stampeanceler, the tubular handle having apertures in its base,combined with a swinging bar suspended in said handle,` and havingserrated feet or prongs working in the apertures, substantially asdescribed.

2. The tubular handle having an apertured base, combined with a swingingbar suspended from the upper part of the handle, and having serratedfeetor prongs working through th e ap ertures in the base, substantially asdescribed.

3. The tubular handle having an apertured B and push the lower end ofsaid bar forward IOO from the upper part of the handle, and havingserrated feet or prongsy Working through the apertures in the base, andthe sliding sleeve operating to swing said bar, substantially asdescribed.

4. rlhe swinging bar suspended from the upper end ofthe tubularvhand-le,having serrated feet or prongs at its lower end, and an intermediatebend or incline, in combination with said handle, and its sliding sleevehaving a lug operating on said incline7 substantially as described.

5. The swinging bar adjustable at the upper end of the tubular handle,and having serrated feet or prongs at its lower end, in combination withsaid handle having apertures in its base
